Current sense amplifier survives
overvoltages
A high side current sense amplifier combines very quick response times with an input voltage range of 4 to 60V.
Linear Technology's LTC6101 high side current sense amplifier combines very quick response times with an input voltage range of 4 to 60V The LTC6101 can withstand voltages up to 70V, a valuable feature when power supply failures or catastrophic load changes can lead to transient overvoltage

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
With a response time under 1us, the LTC6101 is ideal for automatic power shutdown under fault conditions.
The LTC6101 is designed to extract a small differential signal from a high common mode voltage, and then amplify and translate this into a ground-referenced signal.
Achieving this functionality with precision has typically required a combination of discrete components and op amps, differential amplifiers or instrumentation amplifiers.
The LTC6101 simplifies this task by requiring only the LTC6101 ThinSOT package and two resistors.
Not only is this part much smaller and simpler, it consumes only 250uA.
The LTC6101 includes outstanding performance: maximum input bias current is 170nA and maximum input offset voltage is 300uV.
Better than 1% accuracy can be achieved using precision gain resistors, allowing for excellent measurement resolution and the ability to accommodate inputs with large dynamic range.
"The LTC6101 solves many current sense design problems", says Brendan Whelan, Design Section Lead for Linear Technology.
"With the LTC6101, we achieve high voltage, high precision, fast response time and flexibility in a tiny SOT-23 package".
The LTC6101 is in full production, with prices starting at $1.04 each in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
